Answer:
0.766 is the answer for the question
What I would do is start with the price of the dessert and the sales tax $3.85+ $1.15= $5. I started with this because when you add the cents they equal a dollar which makes it easier to continue.
Then I would add the 2.75. This would be 7.75.
Then add 7.75 + 8.50. To simplify this, you can add 7 + 8, then .75+ .50
Which would equal 15 + 1.25 + 16.25
Answer:
The difference between the largest and the smallest shares is $280
Step-by-step explanation:
Total amount to be shared = $560
Ratios of share are 2:3:9 => Total of 14 equal portions
To get one portion, $560 / 14 = $40
First share is 2, therefore $40 x 2 = $80 (smallest share)
Second share is 3, therefore $40 x 3 = $120
Third share is 9, therefore $40 x 9 = $360 (largest share)
<u>TOTAL = $560</u>
The difference between the largest and the smallest = $360 - $80
= $280
53) Vertical angles are congruent, so 
54)
and
are supplementary, so 
55) Because vertical angles are congruent,
. Now, because DR bisects
, this means 
56) This is a geometric sequence where the next term is obtained by multiplying the previous term by -2, so the next two numbers are 16, -32
Answer...

Steps....
1) Rewrite the decimal number as a fraction with 1 in the denominator
2) Multiply to remove 4 decimal places. Here, you multiply top and bottom by
= 10000
3) Find the Greatest Common Factor (GCF) of 2800575 and 10000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 25
4) Simplify the improper fraction!
